C.E.A - Colon Cancer Marker

CEA (carcinoembryonic antigen) is a protein found in the tissues of a developing baby. CEA levels normally become very low or disappear after birth. Healthy adults should have very little or no CEA in their bodies. A CEA test is used to monitor the treatment of people with colon cancer. However, CEA can be falsely elevated in smokers.

Having an elevated CEA does not mean you have cancer but you may require a colonoscopy for further investigation.
